TSM-12 Dual Source 12 Zone Speaker Selector w/ Amplifier Protection

Pin It

Product code: OSD-TSM12

Features and Specifications:

If you want a powerful speaker selector, the TSM-12 is a highly efficient dual source, impedance-matching speaker selector. It will handle more power and in cooler temperatures than the resister based speaker selectors. This high quality speaker selector is designed for use with either 4 or 8 ohm speakers. The A/B switch located on the front panel allows all your speakers to be driven from either of two amplifiers.

The TSM-12 speaker selector is equipped with a low-frequency protection circuit to reduce subsonic signals. This allows higher power operation without amplifier shut-down. Utilizing audio-grade impedance-matching autoformers, the TSM-12 is capable of maintaining a safe operating load at the amplifier while distributing maximum power throughout your system. The TSM-12 is equipped with a rotary switch, located on the rear panel, which is used to set the appropriate impedance to be seen by your amplifier, based on the number of pair of speakers connected. This switch selects the proper taps of the autoformers, allowing the amplifiers power to be delivered safely to the speakers.

If the AMP is 16 ohm and the speakers are 8 ohm with a total of 12 pairs of speakers what would be the correct setting for the rotary switch. Also, each pair of speakers has a VMS100 set at the default impedance matching setting.

By Customer Service - Q&A on May 4, 2012

Answer:

Hi Michael,

We�ll need to know what amp/receiver you are using that is rated at 16 ohms. Technically, if you have a 16-ohm amp and 12 pairs of 8-ohm speakers, you need a 24x setting. You mentioned VMS100 Volume Controls set to default. It features four settings: 2x, 4x, 8x and 16x. Perhaps bypass the protection of the TSM12 (set it at 1) and set all the volume controls to 16x. Please let us verify the amp information, however, and whether you are connecting a volume control for each of the 12 zones.

I have 9 pairs of speakers in my house that all run into a single wire bundle with a lead going to a single 8ohm 100w amp, which keeps shutting off. I put all the impedance jumpers on the room sound controls to x8 and that sort of fixed the amp cutting out most of the time. I have another amp that is a 2x100w, 2ch stereo amp that i want to try, can install this speaker switch using both channels (A & B) from my other AMP to power the spkrs--meaning can i run 5 pair on Ch. A and 4 pair on Ch. B? Or does this switch only allow you to run all 9 pairs on EITHER Ch. A OR Ch. B? Thanks.

Answer:

Hi TD:

it would help to know what two amplifiers you actaully have already. Knowing the capabilities of each amplifier/receiver would help determine which would be best for the following. Thinking that one of the amps would work we would recommend purchasing a combination of our DSM6 and DSM4 speaker selectors. You mentioned having Impedance matching volume controls already. I would connect the DSM6 to Speaker A output and drive five pairs of speakers through a volume control for each pair. Then connect the DSM4 to speaker output B and drive the remaining four pairs again using Volume Controls. The first five pair would be set at 8X and the second four pair at 8X to be on the safe side. You can connect your second amplifer/reciever to both DSM as well. This time to the Source B input on each speaker selector. So you would connect Speaker A to Source B of the DSM6 and Speaker output B to Source B of the DSM4. Again depending on your Amplifier capabilities this would give you control over all 9 speakers while adding the capaility of having two sources to pick from for each speaker throughout the whole system.

By Rodman from Philly, PA on March 19, 2012

How big or what kind of amp would I need for this to work well in my store?

By Customer Service - Q&A on March 19, 2012

Answer:

Rodman,
Our Amp300 could drive 12 zones, depending on their power handling of the speakers.

By eric from tacoma wachington on December 15, 2011

can you hook two tsm-12 dual source zones together

By Customer Service - Q&A on December 16, 2011

Answer:

Hi Eric,
We do not recommend you daisy chain these off of a single speaker output. The only exception is if you are using a high current amplifier like our AMP300: http://www.outdoorspeakerdepot.com/stereo-amplifer.html

You would have to connect one TSM12 to Speaker A and the second TSM 12 to Speaker B.
You must make sure you set the protection switch on the rear of the TSM 12 to the proper setting. This will not work using a second zone output from an Audio/Video Receiver or using a cheap 8-ohm power amplifier.

Thank you for considering OSD Audio

Can you confirm the following configuration: Receiver amp source (rated 300 watts @ 8 ohms, 550 @ 4 ohms) channeled through the TSM-12 , then routed to 300 watt stereo in wall volume controls, and terminate to the ICE 840TT dual cone stereo speaker.

By Customer Service - Q&A on April 27, 2012

Answer:

Brad,
Those components all sound compatible. As long as the amp/ receiver is stable at 8ohms.

By Customer Service - Q&A on May 1, 2012

Answer:

Hi Brad:

Make sure the impedance setting on the Volume control is 1/2x for each pair of speakers you have connected through the volume controls. Then set the protection on the back of the TSM12 to the corresponding number of speakers connected to the speaker selector. Check the owners manual for use with 4 or 8 ohm loads.

By Jason from california on April 27, 2012

Can you hook up a stereo/receiver (home theatre receiver) to the TSM-12 or do you need an amplifier as well?

By Customer Service - Q&A on April 27, 2012

Answer:

Jason,
To drive 12 pairs of speakers we would recommend adding a good high current amplifier like our AMP200 or AMP300. Usually the second zone output using the internal amplifier does not provide enough output. Most AV/Receivers feature a pre-amp output which allows you to add a good external amplifier to drive multiple speakers in conjunction with a speaker selector like the TSM12.
